Hello, I am trying to fit a nonlinear model of the form of: A*x^b*exp(-c*x) This represents a lactation curve. I have a bunch of cows, so I want COW to be a random effect. I have been trying the following code with very littel success: > fm1 <- nlme(yield ~ A*(DIM^B)*(exp(-C*DIM)), + data = group, + fixed = A + B + C ~ 1, + start = c(A = 20, B =

hi all, I've read trough the list and see discussions with similar problems. I've setup a file server and users can connect to it via SMB/CIFS. Windows users just happy. The problem starts with the Mac users. All Mac users are using OS X (versions 10.2,10.3). I'm vetoing several files right now, permission inheriting turned on, I've forced the create mode and directory mode to

Hi folks, I am trying to install the sna package on a MacOS X 10.3.9 and 10.3.4. In neither case I have been able to get the R CMD Install command to succeed from the Terminal window. With 10.3.9 I get an error with the Make command, and with 10.3.4 I get an error on the Description(???) Has anyone out there been able to install it successfully on a Mac? Thanks Alex

Dear R-gurus, I am pretty much new on R. I am trying to to do a repeated analysis of a linear mixed model with R, and I consistently fail... The problem is: Cow is the random factor, treatment is the fixed factor. The dependent variable is milk yield, which is measured several times (repeatedly over time), thus there is another variable which is time (i.e. week). The model would be
